The core of SRT toroidal transformer has circular section. It is different from old toridal transformer. It inherits and raises the excellency of the R-core. Its character is incarnated on the core whose bottom is a half-circle curve. So it can effectively reduce the leakage flux at their verge and reinforce the performance of toroidal transformers. Our toroidal transformers are made by high quality silicon tape (0.23~0.30mm).

SRT toroidal transformers not only have many characters of R-core transformers, but also have many characters not provided by common toroidal transformers. Such as low no load current, low noise, small size and better excitation. SRT toroidal transformers are widely applied in all kinds of electron equipments such as acoustics and computers.
